Embodiment
The sensor of Fig. 1 to Fig. 3 is attached on the axle, and this axle has the first shaft part 1 and the second shaft part 2, the first shaft parts 1 for example are the steering column shaft of motor vehicles steering mechanism, the pinion shaft that the second shaft part 2 for example turns to for so-called motor vehicles.Two shaft parts 1 and 2 are connected to each other by torsion bar 3.
Attached the first gear 4 with a plurality of tooth N1 is so that along with the first shaft part 1 rotates.The second gear 5 with identical number N of teeth 1 is connected with the second shaft part 2.The first gear 4 and 6 engagements of the 3rd gear, the 3rd gear 6 has the second number N of teeth 2, and for the purpose of ratio of gear, the second number N of teeth 2 is usually significantly less than number N of teeth 1.The second gear 5 and the engagement of the 4th gear 7, the 4th gear 7 have the module identical with the 3rd gear 6.In addition, the second gear 5 and the engagement of the 5th gear 8, the number N of teeth 3 of the 5th gear 8 is equally significantly less than the number N of teeth 1 of the second gear 5, but it is different from number N of teeth 2 and in fact preferably differs at least one tooth.
The first magnet 9 is distributed to the 4th gear 7, the first magnets 9 and is rotated together along with gear 7 and magnetized by diameter ground.
The second magnet 10 is distributed on the 5th gear 8, and the second magnet 10 rotates along with the 5th gear 8 and magnetized by diameter ground equally.
Should be understood that the 4th gear 7 can be made by nonmagnetic substance.
The 3rd gear 6 and the 4th gear 7 can be around common rotation axis 15 rotations, and rotation 15 is parallel to the rotation of axle.
The second magnetic sensor 16 is positioned in the central opening 20 of the 3rd gear 6.In addition, a plurality of magnetic flux guides 17 and 18 of coupling arc section shape magnetic guiding part 12 and 13 quantity are attached to the 3rd gear 6.In the sectional view of Fig. 3, magnetic flux guide 17 and 18 is essentially L shaped, and in each case, a supporting leg gives prominence to and terminate in there slight gap 19 in the direction of arc section shape magnetic flux guide 12 and 13, and this interval 19 forms clearances.Magnetic flux guide 17 and other supporting leg of 18 are parallel to the plane of the 3rd gear 6 and extend, and one of these horizontal support legs a side of the 3rd gear 6 extend and these parallel supporting legs in another opposite side at the 3rd gear 6 extend.Therefore, the second sensor 16 is between two horizontal support legs of magnetic flux guide 17 and 18, and for this reason, the 3rd gear 6 has recess 20.The second magnetic sensor 16 is kept by pin 21, and pin 21 is attached to fixedly bar shaped conductor plate 22.The opening 23 that pin 21 is passed in the horizontal support legs of magnetic flux guide 17 is outstanding, and electric conductor is directed into the second magnetic sensor 16 by this pin.
As substituting of pin 21, also can only support the second magnetic sensor 16 with electric conductor, if they have sufficient physical strength.
Arc section shape magnetic guiding part 12 and 13(are on the one hand) and magnetic flux guide 17 and 18(are on the other hand) be placed to so that points to the magnetic flux guide 17 of magnetic guiding part 12 and 13 and 18 supporting leg is in the neutrality setting, the neutral setting by zero angle of torsion limits, directly over the interval 14 between two arc section shape magnetic guiding parts 12 and 13.Therefore, magnetic circuit between the utmost point of arc section shape magnetic guiding part 12 and 13 extends through the supporting leg mentioned above of magnetic flux guide 17 and 18 and the gap of wherein placing the second sensor 16, so that still generating output signal not of magnetic field and the second sensor 16 do not occur between the horizontal support legs of magnetic flux guide 17 and 18.If between two shaft parts 1 and 2, angle of torsion occurs, the 3rd gear 6 and the 4th gear 7 differently reverse so, so that the passing 14 formed clearances, interval and back-out towards arc section shape magnetic guiding part 12 and 13 outstanding supporting legs of magnetic flux guide 17 and 18, and via magnetic flux guide 17 and 18, magnetic field is directed to the second sensor 16, the second sensor 16 transmits output signal proportional to magnetic field intensity, and this output signal is the measured value of angle of torsion to be measured.
The 3rd sensor 25 of distributing to the second magnet 10 is designed to be similar to first sensor 11 and is attached to fixedly on the bar shaped conductor plate 24, and first sensor 11 and the 3rd sensor 25 can be attached on the common strip conductor plate 24.Because the 4th gear 7 has the different numbers of teeth (N2 and N3) from the 5th gear 8, its preferably difference be at least 1, so in a known way, also can detect angular region above 360 ° for the rotation angle of the second shaft part 2.
The N1:N2 ratio of gear of gear is depended in the sensitivity of being responsible for the second sensor 16 of angle of torsion basically.Ratio of gear is larger, and is larger (if there is angle of torsion in two gears 6 and 7 relative torsion relative to each other) just.
But, the essential very minor diameter of high transmission ratio the and therefore number of teeth of the 3rd gear 6 and the 4th gear 7 is less.Because in fact these gears 6 and 7 be made of plastics, the number of teeth can not be made for as required little, because if shaft part 1 and 2 rotates rapidly, so can be owing to high temperature appear in friction, and so to the more galling of gear.
However, in order to obtain the higher measurement sensitivity of angle of torsion and the resolution characteristic of Geng Gao, stipulate to use multipole axial magnetized magnet and more substantial magnetic flux guide according to the of the present invention other embodiment of Fig. 5 to Fig. 7.
In the embodiment of Fig. 5 example, place the multi-pole magnet with six arc section shape magnetic sections 26,27,28,29,30,31, these magnetic sections alternating magnetization in north orientation and south orientation at the 4th gear 7.Quantity corresponding to arc section shape magnetic section, corresponding a plurality of magnetic flux guides 32,33,34,35,36 are set, 37, and magnetic flux guide 32,34,36 is connected to each other and its horizontal support legs extends in a side of the 3rd gear 6, and other magnetic flux guide 33,35 and 37 is connected to each other and its horizontal support legs extends at the opposite side of the 3rd gear 6.Because this layout, the resolution characteristic for the angle of torsion measurement that less relative rotation angle causes the larger variation in magnetic field on the second sensor 16 and therefore causes improving between the 3rd gear 6 and the 4th gear 7.
For this embodiment example, according to a modification, the first magnet 9 can be provided as the magnetized magnet of bipolar diameter, as in the embodiment of Fig. 1 and Fig. 3 example, and the each other decoupling zero by magnetic shield panel 39 at the first magnet 9 on the 4th gear 7 one sides and the multi-pole magnet on the 4th gear 7 opposite sides is so that the first magnet 9 has the function identical with the first embodiment example.According to a replacement scheme, the first magnet 9 also can be replaced by magnetic cable, magnetic cable extends through the South Pole and the arctic of multi-pole magnet, and multi-pole magnet passes the 4th gear 7 and passes opening in the magnetic shield panel 39, passes to the first magnetic sensor 11 with the corresponding magnetic field effect with bipolar magnet.
And use multi-pole magnet to have the following advantages: when torque occurring, the magnetic field intensity that acts on the second sensor 16 that causes is stronger than the situation of the bipolar magnet 9 of the embodiment example of using Fig. 1 to Fig. 3.
For the purpose of comprehensively, again mention all gears 4 to 8 and made by the nonmagnetic substance such as plastics.Gear 6,7 and 8 remains in the tension frame of Known designs, such as described in DE 199 62 241 A1 like that.
